I Specification of Letters Intent.

Patented Dec. 9, 1913.

Application filed June 28, 1809. Serial No. 504,720.

To all whom 2'27 may concern lie it known that l, Plum? T. Donor, of li'nshington, District of Columbia, have invented a new and useful. improvement in 'lyp-c Casting and Composing lllachines, or which the following" is a specification.

in commercial line casting machines, suchtor instance. asarc represented in U. S. Patents +6.53: and 557,000. commonly known as l'inotype machines, matrices bearing individual. characters are assembled together with cxpunsible, double wedge spacers in a continuous line; the line is elongated and justified by the relative movement or" the wedges in each spacer; and is presented momentarily to close the' face of a slotted mold into which molten metal forced against the matriws to produce a solid or continuous line-printing slug bearing upon one edge the characters in the order in which they will appear in the printed line. In these nachiues the matrices containing the various characters are of a thickness corresponding to the set. of the characters therein; or in other words, each matrix is of a thickness equal to the width of the contained character plus its side spaces. technically known as side bearings.

The aim of this invention is to modify muchincs of this class to pr0duceinstced of continuous slugs--s1ngle type and spaces in lines of a uniform and predetermined length; and to produce such type and spaces without using special matrices or special wedge spacers other than those in commercial use in such line casting machines at the present day. To this end I preserve the general organization of the machine as regards the matrices and spacers, and the composing and distributing mechanisms; butintroduce a mold or molds adjustable setwise and such new devices as will, when the composition and justification of the line are complete,-

justify it, subdivide it into its primary ele- -mcnts or units of single matrices and 51d .ation therein. to directly control the adjustment of the mold during their coiipcration therewith. so that the resulting, type must have precisely the same set; or in other words-the same width running-wise of the line, as the matrix or spacer.

I am aware that a type casting and setting machine has been proposed in which matrices all of one thickness were provided with the characters or matrices proper in their broudside faces. which faces were pre sentcd to and widely overlapped the mold. The faces of these matrices were made of variant Widths tocontrol the adjustment of the mold. but the width in all cases was greatly in excess of the set ,7 or width of the character, the matrices being. in fact ma terially difiereut from those used in the linot-ype machine, and incapable of being presented edgewisc to the mold.

In a modified line casting machine such as is here disclosed, the matrices and spacers may be stored in their reguhir magazines. and the line may be composed in the usual assembling block or elevator by the operation. of the ordinary keyboard and Magazine escapenient devices; the line is then transjustificd-the lower wedge of each spacer being driven upwardthroughthe line as usual to justify the line to the predetermined lengthand heldt'or subdivision into its primary units. So far; the usual driving mechanism has been used to actuate and control the various subsidiary devices. This main mechanism is now arrested and a secondary driving mechanism is thrown into action to effect the line-subdivision, the unit transfer, and the unit casting. This secondary or auxiliary mechanism operates the rotary mold carrier, the casting, and the ejection devices, at the same time effecting the transfer of the singlematrices and spacers from one point to another. As each matrix or spacer is carried down from the delivery channel in succession and presented edge wise to the mold, the type or space is cast in the latter. the construction of the mold being such that it automatically determinesin consequence of its adjustment by the varying thicknesses of the matrices presented to it the setwise thickness or size of the corresponding type cast within it. After being presented to the mold each matrix and spacer is transferred to the first elevator which, when the casting operations are colt;-

ferred to the delivery channel and is there.

by the regular mechanisms the spacers? and wedge spacers, series thicknesses to an understanding of the principles and i sell.- in its application material change inthe results produced.

ing mechanisms,

cated lines in Fig. 1'. 3 tion through the machlne from front to rear,

pleted, will contain within it the entire line assembled. At this point, the secondary mechanism is, in its turn, arrested, and the. main driving mechanism resumes its inter rupted revolution. The elevator in which the line is stored rises as usual, and the line is disintegrated inthe'intermediate channel passing Into their magazine, and the matrices lacing elevated to the distributing devices for distribution to their appropriate channels in the magazine.

I believe it to be broadly new to cast in such a modified, commercial line casting ma chine, from assembled lines of commercial matrices having the characters in their edges of separate types and spaces which will, when assembled, form lines of a uniform and predetermined length. I also believe-it to be new to determine. the setwise size of the type or spaces cast in the mold, through the automatic ad justment of the mold by the adjusted wedge spacers in connection'with matrices having corresponding to the widths of the individual type to be produced.-

While lhave' represented my invention as embodied in a commercial Mergenthaler linotype machine of the general organization shown in the above named patents, and

have limited the accompanying drawings of thy improvements and the related parts-ethat machine to such only as are necessary mode of action of my inventioruyet I desire it to he understood that I do not restrict myself to those inechanical foi'ms and move-- ments in the terms of which I have expressed my: invention, nor do I restrict my" to the Mergenthaler type of line casting machine only.

,As the basic el ments of my machine I employ a series of circulating matrices and spacers, such as are shown in Figs. 27 and 28, their construction being the same as that of those used at the present time in the coinmcrcial lvlergenthaler machine. Each matrix has in one edge a. character or matrix proper, and in the upper end a series of dis- Figs 39 is a side elevatributing teeth. Each matrix has thin walls alongside the character, but has a total thickness equal to the set or width of the type to be produced therefrom. From oppo-- site edges, at each end, project symmetrical lugs or cars. Each spacer is composed of two oppositcly-tapered wedges permanently connected by a sliding joint, one of the wedges being provided with cars whereby it may be locked fast in the line, while its complementary wedge is driven upward endwise through the line, increasing the width of the space in the line occupied by the spacer, and expanding the line in length by a corresponding amount.

Referr'ng to the drawings, the main frame of the machine; B and C represent res actively the matrix and spacer magazines represents the assembling elevator, these parts being all such as are used at the present time. in linotype machines. The upper portion of the'elevator D is horiatafiy channeled and formed to receive sustain in the composed lines matrices and spacers F shown in the various figures.

(l and G represent two fingers depending from horizontal slides mounted in the main frame and connected by a contractile spring,

, which tends to draw the fingers together.

These parts cons tute what is commonly known as the line transfer carriage and show u ilg. 7.

lingers G, G, the tr carriage, holding the composed line between the fingers G,G is now free to be moved to the left by the usual operating devices, thus carrying the line out of the elevator D and into the stationary delivery channel I shown in Fig. l. The line being thus held at rest in the channel I, the

frame J rises to the position shown in full lines in Fig. 1, with its upright. side arms in position to embrace or confine the fingers of the transfer carriage during the elongation and justification of the line. When the frame J is in this upper position, the justifying bar K rises and pushes the lower wedges of the spacers l? upward through the mail-itline, causing the elongation or justificatio'a of the line to the prescribed length. As soon the line has filled out tightly between the confining arms, the resistance of the matrices arrests the rise of the wedges.

The distance through which the bar K 'risesthat is, the amount of expansion in 1 each wedge spacer--1s reproduced in the use i A represents of the step is, which occurs at the same time. This step is an extension of a slide which also has an extended portion k overlying a projection on the rod .2 which lifts the bar K.' As the rod Z1 rises to effect through K the justification of the line, it lifts the step is simultaneously and to the same extent. When the rod descends after justification has been completed, the'step la remains in its elevated position, and upon its top face the bottom part of each wedge spacer rests during the casting of the space therefrom, as shown in Fig. 15.

The step'k, with its associated parts is shown in Figs. 8-12. The slide 70 moves up and down in the main frame A and is retainedin its groove by plates is and 7c, overlying its rear face. In its front face is inserted permanently a toothed bar is, cooperating with a spring'held pin 7& to secure the retention of the step at any elevation to which it is raised by the act of justification. The pin is is freely attached to a lever 71; the lower portion of which is pivoted to the frame A and extended into the path of the link The lifting of this link carries the upper part of the pivoted lever it away from the frame, effecting the disengagement of the pin 767 from the toothed portion of the slide iv, and leaving the latter free to descend to its lowest and inoperative position. The springiv", secured at one end to the frame and at the other to the slide, may be used to facilitate this downward move-' ment. It will be seen therefore that immediately before the justification of each line the step 7: is restored to the lower posi tion. I

The justification of the line once effected, the line-confining frame J descends to its lower position, followed by the bar K. The

line is then free to be moved by the usual operating devices still farther to the left until the upper ears of the first matrix in v the line encognter the shoulders Z at the end of the horizontal rib Z in the channel I. The fingerGof the transfer carriage moves still farther t9 the left, however, until it reaches the position shown in Figs. 14 and 16, in which position a space is seen to exist between it and the first matrix in the line.

The shift carriage L, by means of which the lineof'matrices and spacers is subdivided into its single units, travels vertically in this space between the finger G and the matrix line to transfer the units to the casting mechanism.

The pa wls Z are in such case attached to small, springmetracted levers Z pivoted in and operating Within a recess in. the side walls of the channel 1 and having a free end projecting slightly into the path of the shift carriage L. In each of its upward ,movementsthe shaft carriage encounters this projecting end and carries it upward with it, thereby elevstingthe lifting, pawls hasjust been described,this

Z, and with theni the first unit in the line. As soon d 'this first unit is lifted sufficiently to allow itstears to clear the detaining shoulder plates Z, the pressure of the rest of the line behind it caused by the tension of the spring g, drives it forward into the shift carriage as shown in Fig. 16. In the carriage it is sustained in a pendent position, its upper ears resting upon suitably disposed shoulders or ribs. The transfer of the unit thus accomplished, the shift cer-v riage descends to presentv the unit to the casting mechanism. and the lever Z retracts the lifting pawl Z thus allowing the next unit in the line to bank against the detaining shoulder plates Z. This line-subdividing and 'u'nit'transfeinring operation is re peated successively. for each separate unit in the line. i y

The movement thus'derived from t ie varying contour of the cam face in motion is communicated through the link Z to the second lever l", and from it, by means .of the link connection'lflto the shift carriage L. The mold carrier ll has mounted upon it'four separate molds, 5. and makes one-quarter of a revolution for each complete cycle "of casting operations,

thus effecting through the four-point cum, n, i one complete upward and downward transfer movement of the shift carriage L for each casting cycle.

N represents the rotary mold carrier fwhich, together with its four separate moldsand its intermittingly actuhting 'connec tions, is clearly shown in Figs: 30 and 31, as well as in the general views shown in Figs;

The carrier N is mounted as. usual. in the mold slide N the latter being; free to reciprocate to and fro as is customcry in machines of this kind, and beingwuctug0 eted and controlled in this reciprocating movement by mechanism to be described The carrier is secured in place upon the slide N by the pin 12. and the nut n heingfree to rotate thereon as desired.

i oai eas with the driving pin 8. gear 8 causes the driving disk 8 to engage the follower s, the driving pin entering one ot' the slots in the latter as shown in Fig. 30,-ai1d producing a quarter turn of the follower. The driving pin 5, having passed outof the long-slot in the follower, and the locking disk 8 having engaged with its edge the corrcspondin" edge of the latter, the further rotation or the driving disk does not for the remainder of its movement cause any rotation of the mold carrier N. The carrier reinainsloclred in the position in which it has been left by the driving pin until the latter completes its revolution and engages the follower in the next slot. It will thus be obvious that for each full revolution of the driving disk 8, the mold carrier makes one quarter ot a turn; and it will he noted also that owing to the manner in which these cooperating parts are formed the forward movement of the carrier during its idle intervals does not disengage the follower a from the lockihgdisk s The molds M, M M, M are of similar construction, and are clearly shown in Figs. 23%26. To the body portion at is secured at each end of the mold uprights m and 122?, to which and l1 etWeen which is fastened the cover plate m. The cap portion m slides horizontally between the body wt, and cover plate m a projecting key on the cap and a corresponding groove in' the cov -r plate serving to guide and regulate this to and fro movement of the cap. A suit-able spring of placed in a recess in the cap, tends constantly to force it toward the night and to thus close the mold cell, as shown in Fig: 26. vThe pressure of'thc spring m is resisted by the detaining'pavvl m pivoted in the cover plate m, and having one end formed to engage in a. recess in the sliding cap, while a spring? beneath the opposite end tends to make the pawl preserve this engagement. 7

The right hand'mold liner m is attached to the mold body by a screw or similar fastening, themold body having raised ribs or projections m" front and back of the liner to preserve its alinement. The front edge of the liner is extended at one side to form the vertical jaw m projecting in front of the mold and extending above and below the plane of the mold cell. on? is secured to the sliding cap, by means of screws or other fastenings. The inner faces 7 of these jaws are in line with the correspondin "faces or ends of the mold cell, and contact with one another when the mold cell (awning is closed.

When any one of the molds has been.

moved by the carrier to the upper or casting: position, ready for presentation to the line unit in the shift carriage L. the mold cell always opento the full width, as shown A similar jaw The motion ozt tlic in Figs. 95 and 26. As the mold begins to advance upon the line unit the release pin m in the cover plate, encountering the rear vertical lace of the carriage L, as shown in engages with its beveled upper face the similarly beveled under face of the detaining pawl m in such a way as to disengage the pawl. from the sliding mold cap m. Under the pressure oi the spring m the cap slides to the right, thus clamping the line unit firmly between the projecting jaws m3? and m and contracting the mold cell in Width to register exactly with the Width of the line unit. I have shown in Fig. 25, this relation of the line unit and. the two clamping jaws, and have also indicated the movement of the jaw attached to the sliding mold cap by full and dotted lines;

lit will be noted that the mold is thus so constructed that the sliding cap adjusts itself automatically to the varying thicknesses of the matrices or spacers; and that the set-Wise size thetype or space cast in the mold is thereby determined automatically in each case by ths'thiclrnessot the line element itself. it also to be noted that the same matrix surfaces and dimensions which are rtilized in justifying the line aroused to deter; 2 the adjustment of the mold In other words, the thickness of the matrices d adjusted-spacers deter-mines the length of; the line and also determines the adjustment of the mold, no additional or special sur'fnces or dimensions being required for the in e.

It may be here remarked that when the assembling elevator B, and the latter lifted to'its upper position, the release of the line transfer carriage {i G starts the machine in the usual way. The driving clutch shaft begins its regular rotatii'in. The ine confining and justifying operations and the subsequent movement of the line transfer carriage to the left are each governed. and controlled by their appropriate cams on this shaft. Its stoppage in the manner just described is timed to occur after the justifiea tion of the line, and as soon as the latter has been moved by the transfer carriag. to the left so-that the ears of the first matrix in the ins are banking against the detaining shoulis now engaged with. the clutch in mesh with the gear is of the secondary mechanism and thus brings into action the before described.

As the gear rotates the pin encounters the pawl, carries it around its .pivot point into a more vertical position, and then draws it forward together with its associated parts'to the position shown in Figs. 4- and The effect of this forward movement of the arm a is to disengage the finger-r f'from the cam surface 1" on the main gear 1' The clutch lever 1' is imme diately drawn back into its original position' by; the spring r,disengaging the driving clutch r from the secondary driving pinion r and engaging it with the main driving pinionr ,thus stopping the ond ry mechanism and starting the main cam shaft again in its interrupted movement.

The first elevator O. which contains within it the entire line of matrices and spacers and which is operated from the cam O in the usual manner, is now raised to theupper position shown by the dotted lines in Fig. 1 that the line may be transferred to the intermediate channel V and there disintegrated in the'usual way. Just before it rises, however, the line transfer carriage finger G is moved slightly to the right by .its controlling cam and, upon the descent ofthe elevator to its lower position, this carriage is moved fully to the right until itoccupies its original position above the assembling elevator D, in readiness toireceive the next composed line.

The cams J and K shown in Fig. 5 operate through the leversy' and is respectivelythe flevers being spring-held constantly against their respective cam faces in any suitable way,to lift'and depress the rods 3' and shown in Fi 1.; thus actuating by means of the pivoted links j and 7: 3 the line-confining frame 3 and the justification bar K in theirirequired and appropriate movements.

The movements and operations (if all the 5 various parts and members may now be cam shaft is operated the usual leverby;

The cam g now allows the line transferfingers G' G to move fartherto the left until the line isin pesitionfor subdivision, and immediately afterward the cam surface 2- on the main gear 1" throws the clutch 1' out of engage-.

makes one quarter of a turn, during which 'the shift carriage rises to the line and the unit transfer takes place. The mold slide advances, and the line unitis clamped between the confining jaws of the mold. Meanwhile the pot and ejector have advanced. and the lock-up takes place,the type being cast and the previously-cast type being ejected at the same time.- The mold recedes and it does so the transfer finger pushes the line unit from the shift carriage into the first elevator O. Theamold slide,

the ejector, and the pot recede fully and the cycle is complete. The mold carrier makes another quarter of a turn, beginnings, new cycle and so on,the operations proceeding successively until the last line unit has passed the casting point. In the nextand idle cycle which occurs after-this hasbeen accomplished, the sliding mold cap closes the mold cell entirely, and in so doing encounters a finger on lever U which communicates this slight abnormal movementtoa drop pawl n lying n rt'nally in'an-inoperative position out of t e pathway of a pin traveling on the side of the gear S. The pawl swings'into the pathway of the 'pin,

the latter encounters it and moves it in a' forward direction, thereby effecting the dis-. engagement of the driving clutch 1 from the driving pinion of the Secondary mechanism, and allowingit to rengage with the main driving pinion,-thus stopping the secondary mechanism and re-starting the main shaft in its interrupted ayptation.
